BMW of Westlake - Service Center

I have abandoned this dealer a long time ago. I had an X5 which was bought from a Ganley Ford and it has about 20k miles on it. So i worked with Ganley while my vehicle was under warranty. I even extended it which was bought from a Ganley Ford and it has about 20k miles on it. So i worked with Ganley while my vehicle was under warranty. I even extended it to 70k. For a while before running past 70k my car needed a sensor changed. When i got it back the car ran ok for a while at least.. Then it overheated badly and i shut it off immediately with no warning whats so ever about the temp of the car...I get out of the car and the hose that should never come off by itself was out...obviously someone at Ganley when they changed that sensor they forgot to secure that hose. Obviously the car was out of its warranty by about 2k miles so they left the billing up to me. ( Dealers you must love them" Upon taking looking at the lose hose i find a substance on its walls a white hardened substance. We find out that its a temporary fix liquid that hardens in order for the vehicle to not leak. I kept telling them that coolant was leaking and their reply was a mere 'we pressurized it and it is fine' After I took the car in...they told me that this happened because there was in fact a coolant leak but it was an 'internal coolant leak and that is not the same thing' . So after all there was something wrong with my car while in warranty, but they didn't find it until it went out of the warranty.....They tried to bill 5k More
